During India's tour of Australia in 1947-48, Indian all-rounder Vinoo Mankad ran out Australian opener Bill Brown at the non-striker's end. This was not the first instance of such a dismissal, but it became the most famous because Mankad had previously warned Brown about backing up too far.
In the tour match before the Test, Mankad had already run Brown out in the same manner. Despite the warning, Brown continued to leave his crease early. In the second Test, Mankad did it again, this time in a match situation.
The Australian media criticized Mankad, but interestingly, the great Don Bradman himself defended the Indian, saying the batsman was at fault for leaving his crease. Bradman's position was clear: the Laws existed to be enforced, and the batsman was gaining an unfair advantage.
The dismissal became known as "Mankading" and remained one of cricket's most debated areas for over 70 years, until the ICC normalized it as a standard run-out in 2022. Every subsequent instance — from Ashwin-Buttler to Deepti Sharma — traces back to this original moment.
